Relying on projects.list was never a great idea and now that we use cgit
there's no need for projects.list anymore. Additionally, we sometimes
need to move a repository to another location (for example when someone
leaves Linaro). The current process for handling this is a pain.
With this change we can automatically handle renamed repositories by
looking at the list of all repositories defined on disk.
